Wellington Panel

Picked this up at NAM on Saturday – allegedly from a Wellington.

Very heavily corroded – some evidence of RAF Dark Green paint on upper surface.

Two inner ribs remaining – one marked with 100 and the other as shown.

The Stamps read A9CB and the remains of numbers XXX302. No other stamps or markings

Any ideas ?

Searched for a few hours but not many pics of the two Wellingtons remaining specifically around the engines – that are of use.

P.S. it is 60 cm long and about 30cm wide in the middle.

There were 8 Dzus fastening around the edge.

The thicker end has the remains of a hatch – but original panel was longer.
